If you want to live a long life, you should eat the most common food. You see those who live a long life are not rural people who only eat the simplest food in the countryside, so they can not live a long life by taking supplements. If so, there would have been immortal people in the world. Of course, the most important thing is to see what that person needs, rather than blindly supplementing it. There are many factors for longevity, such as whether he had a good body when he was young, whether he had any heavy work or injuries, and his current mentality.
